▼ The primary goal of this work is the theoretical and experimental development of micro and mini systems for the photovoltaic production and the energy storage. Robotics platforms should be, as much as possible, autonomous and self-sufficient, also from the energetic point of view. To this aim, up to now, the best compromise appears to be the use of micro solar power systems with rechargeable batteries. The use of this strategy for supplying systems with limited size and mass, but nevertheless high power requirements, such as a mobile robot, has been first studied. The system taken as test-bed in the experiment is a bio-inspired mobile robot, called TriBot. First of all, a preliminary analysis of the feasibility of a photovoltaic system with batteries to supply this mobile robot has been done, considering the different solutions to place the PV cells on the robot structure, the different photovoltaic technologies and the power consumption of the robot, the conclusion is that, using the photovoltaic system here proposed, it is possible to increase the autonomy of the robot. Since in the PV system here analyzed few solar cells can be employed, a very efficient charging system is an essential requisite. To this aim, a novel photovoltaic charge regulator, which uses the Fractional Open-Circuit Voltage MPPT method, is proposed. A typical stand-alone photovoltaic system includes a solar array, batteries, regulator and load. In order to model the whole system and to evaluate its performance, a Simulink model in Matlab environment has been developed. In the simulator, measured values of the radiation and the temperature have been used, Anyhow, it will be possible also to use predicted values of radiation and temperature. In this work, data given us by a weather forecast provider have been used. First of all the accuracy of these predicted data have been determined. Then, a method to classify each minute of a day as variable, cloudy, slightly cloudy or clear has been implemented. Using a neural network, a correlation between the classification of a specific day and the error done has been found. The knowledge of the available energy, in fact, should allow to implement power saving strategies, optimizing the activities of the robot. Forecast and measured solar radiation are relative to the horizontal plane. However, the PV panel exposition is not assumed to be a control variable due to the fact that the robot can change its posture operating on uneven terrains. For these reasons, models are required to estimate the solar radiation on the plane of the PV array starting from the radiation on the horizontal plane. To this aim, Perez and Klucher models have been developed, these models require information at the same time on the global and the direct or diffuse radiation on the horizontal surface. Moreover, a neural network that allows to evaluate the global solar radiation on the tilted surface directly from the global solar radiation measured on the horizontal plane, without the need to slit it into the direct and diffuse…

▼ In this manuscript three related aspects of research on BCI systems were discussed. These aspects were the evaluation of a nonlinear feature extraction algorithm for BCI, the analysis of the functional connectivity between the signals acquired in different brain regions when a user performs an operant conditioning paradigm with fMRI based BCI technology, and the development of BCIs applications for disabled subjects. We have introduced a new EEG signals features extraction techniques based on nonlinear time series analysis. This signal processing approach was tested offline considering three sessions of imaginary motor tasks. The main objective is increasing the performance of BCI systems extracting a more robust feature. In order to reach this objective a fast algorithm that computes the largest Lyapunov exponent, the DivA [7], was used. This implementation results to be computationally less onerous than the conventional ones, since it is not based on the time-delay embedding concept and also no intermediate computational steps are needed to obtain the final result. For this reason the DivA is particularly suitable for real time analysis, thus for BCI applications. Our evaluations underline the capability and the potentiality of this method in respect to the classical approach. The idea for future works is to integrate the nonlinear algorithm investigated in this thesis in a BCI system, thus using it on line. The design of a BCI based on our nonlinear feature extraction method could improve the performance of the systems that use sensory motor rhythms as neurophysiologic signals. The analysis of the functional connectivity between brain regions involved in the perception of pain is the second topic that were dealt with in this thesis. Thanks to the collaboration with the central institute of mental health, Heidelberg university in Mannheim, the dataset recorded with an fMRI based BCI technology have been analysed. The results reveal the possibility for a person to modulate the brain waves, in particular the neurophysiologic signals related to the perception of pain. Control over the pain modulatory system is an important target because it could enable a unique mechanism for clinical control over pain. Here, we found that using real-time functional MRI based BCI to guide training, subjects were able to learn to control activation both in anterior cingulated cortex and in the posterior insula. The BCI techniques could have an important role for treating disease, for example for the chronic pain treatment. An aspect that can be investigated in future work is the involvement of the medial cingulate cortex in the pain perception. Indeed when the subject deliberately induced increases or decreases in ACC or pIns fMRI activation, there was a corresponding change in the connection between the MCC and the other ROIs. In particular a more strong connection between MCC and pInsR can be noticed. In future works could be interesting to analyze the role of MCC in the perception of pain. Finally, we proposed the designs of…

▼ During his history, man has always tried to imitate nature, to better know and understand himself. Thanks to the improvement of electronic technologies, the instruments with which he has followed this target have been improved, with results more and more realistic. Trying to artificially reproduce what nature has slowly realized and time tested, humans find amazing problems and solutions, that give a contribution to their life quality. Robots are the way humans try to reproduce animals, and study their interaction with the environment. Robots help to better know animals and animals help to create efficient robots. Analyzing animal brains leads to new control systems that could allow robots to be able to orient themselves, to take decisions, to survive alone, to complete dangerous missions, to be completely autonomous. Robot implementation could also lead to predictions, for basic science, deriving from emergent properties of models. The goal of this work is to design and simulate a simplified model of the brain of the Drosophila melanogaster. Fly has a small brain that shows a wealth of complex behaviors. Genetic techniques allow to remove parts of the Drosophila brain and the analysis of mutants behavior can lead to hypotheses about the functions of every single brain part. The bio-inspired models have been implemented in robotic structures and in robot simulators, in order to make comparisons between the real fly and the modeled one. This PhD research has been oriented toward two main lines: the first one has been directed to the insect brain modeling; the second line has been oriented to the simulation and the implementation of the model in robotic structures and then to the analysis of the behavior of the robots in order to obtain comparative results with real flies as well as predictions about the behavior of the real flies under particular circumstances. This thesis is divided in seven chapters. The first four chapters describe an original robotic architecture inspired by the fruit fly \emph{Drosophila melanogaster}. In the last three chapters, instead, one peculiar part of the insect brain, the Mushroom Bodies, is analyzed and modeled. This structure presents a lot of interesting capabilities and it deserves attention and investigation. Biological details will be given step by step, in order to emphasize the link between biology and models

▼ In this thesis a set of novel video annotation methods for performance evaluation of object detection, tracking and recognition applications is proposed. Large scale labeled datasets are of key importance for the development of automatic video analysis tools as they, from one hand, allow multi-class classifiers training and, from the other hand, support the algorithms evaluation phase. This is widely recognized by the multimedia and computer vision communities, as witnessed by the growing number of available datasets; however, the research still lacks in usable and effective annotation tools, since a lot of human effort is necessary to generate high quality ground truth data. However, it is not feasible to collect large video ground truths, covering as much scenarios and object categories as possible, by exploiting only the effort of isolated research groups. For these reasons in this thesis we first present a semi-automatic stand-alone tool for gathering ground truth data with the aim of improving the user experience by providing edit shortcuts such as hotkeys and drag-and-drop, and by integrating computer vision algorithms to make the whole process automatic with a little intervention by the end users. In this context we also present a collaborative web-based platform for video ground truthing which integrates the stand-alone tools and provides an easy and intuitive user interface that allows plain video annotation and instant sharing/integration of the generated ground truths, in order not to only alleviate a large part of the effort and time needed, but also to increase the quality of the generated annotations. These tools are specifically thought to help users in collecting annotations thanks to the introduction of simple interfaces, which considerably improve and facilitate their work, also by integrating novel methods for quality control, but still remain a burdensome task with regard to the attention and time needed to obtain good records. To motivate the users and relieve them from the tiresome task of making manual annotations, we devised strategies to automatically create annotation by processing data from the crowd. To this end we initially develop an approach based on an online game to collect big noisy data. By exploiting the information, we then propose data-driven approaches, mainly based on image segmentation and statistical methods, which allow us to obtain reliable video annotations by using low quality and noisy data gathered quickly and easily from the game. Also we demonstrate that the quality of the obtained annotations increases as more users play with the game making it an effective and valid application for the collection of consistent ground truth data.

▼ One of the most interesting aspects of complexity is that it occurs at different levels. It may occur at the level of interactions among the agents that compose a complex network: despite the relatively simple behavior of each single unit, the whole network may exhibit holistic collective dynamics, such self-organization, synchronization, robustness to failure, and so on; and it may occur, in the form of an aperiodic irregular behavior, at the level of a system described by a low-order set of ordinary differential equations, three, for instance, in the case of continuous-time systems. This thesis focuses on both levels of complexity. The first part, in particular, deals with complexity at the level of a single dynamical system. The main contributions of the work summarized in this thesis refer to the use of a new electronic component for the design of chaotic circuits. This new component, the memristor, is at the same time a memory element and a nonlinear element and for this reason has been regarded in literature as an effective block to reduce the minimum number of components needed to build a chaotic circuit. The original aspect of this thesis is the focus on a realistic model of memristor, that is a model derived starting from the analysis of the real memristor device discovered in the HP laboratories. The use of such approach introduces constraints in the design that are not considered in idealized models such as piece-wise linear ones. The main results were: i) the introduction of a configuration of two memristors in antiparallel which has been used as the fundamental block to design a gallery of autonomous and non-autonomous nonlinear circuits exhibiting a rich dynamics, including chaos; ii) the design of a hybrid circuit which takes from the characterization methodology of real memristors the idea of using a simple digital linear control circuitry which allows chaos to be observed with the driving of a single memristor. The second part of the thesis focuses on synchronization on complex networks. In particular, the onset of a new form of synchronization, named remote synchronization, in complex networks has been investigated. Remote synchronization appears in star-like networks of coupled Stuart-Landau oscillators, where the hub node is characterized by an oscillation frequency different from that of the leaves, as a regime in which the peripheral nodes are synchronized each other but not with the hub. In this thesis we have investigated if similar conditions can be observed in more general frameworks. We have found that networks of not homogeneous nodes may display many pairs of nodes that, despite the fact that are not directly connected nor connected through chains of synchronized nodes, are phase synchronized. We have introduced measures to characterize this phenomenon and found that it is common both in scale-free and Erdos-Renyi networks. Furthermore, this is an important mechanism to form clusters of synchronized nodes in a network. Finally, we have linked the appearance of pairs of remotely…

▼ Non-intrusive appliance load monitoring (NIALM) is the process of disaggregating a household s total electricity consumption into its contributing appliances. Smart meters are currently being deployed on national scales, providing a platform to collect aggregate household electricity consumption data. Existing approaches to NIALM require a manual training phase in which either sub-metered appliance data is collected or appliance usage is manually labelled. This training data is used to build models of the household appliances, which are subsequently used to disaggregate the household s electricity data. Due to the requirement of such a training phase, existing approaches do not scale automatically to the national scales of smart meter data currently being collected. In this thesis an unsupervised disaggregation method is presented which, unlike existing approaches, does not require a manual training phase. A NIALM system reads real-time data from a smart meter, usually positioned at the point on the public electricity network at which the customers is connected, and uses algorithms not only to quantify how much energy is used in the home, but also to determine what main devices are being operated. NIALM algorithms need a complete load signature and complex optimization algorithms to find the right combination of single loads that fits the real electrical measurements. It is practically impossible to get the detailed signature of all appliances inside a house/building and sophisticated optimization algorithm are not suitable for on-line applications. To do so, we address the following topics. First, a straightforward NIALM algorithm is proposed, it is based on both a simple load signature, rated active and reactive power and a heuristic disaggregation algorithm. Second, on real applications, this approach cannot reach very high performances; this is the reason why an active involvement of users is considered. The users feedback aims to: correct the load signatures, reduce the error of disaggregation algorithm and increase the active participation of users in saving energy politics. Third, the NIALM algorithm has been accurately tested numerically using as input load curves generated randomly but under given constraints. In this way, the causes of inefficiency of the proposed approach are quantitatively analyzed both separately and in different combinations. The above contributions provide a solution which satisfies the requirements of a NIALM method which is both unsupervised (no manual interaction required during training) and uses only smart meter data (no installation of additional hardware is required). When combined, the contributions presented in this thesis represent an advancement in the state of the art in the field of non-intrusive appliance load monitoring, and a step towards increasing the efficiency of energy consumption within households.

▼ In the last decade the role of context awareness, traditionally focused on human to machine interaction, has broadened its perspectives to the machine to machine paradigma. The main goal of this dissertation is both to understand how to apply context awareness to situations , perceived by smart devices, and to conceptually stretch context modeling to a dynamic contextualization in human to machine interactions. The roots of the Internet of Things paradigma reside in the efforts reached in the Wireless Sensor Networks technology, mostly in data aggregation and in energy saving, and the adoption of multi-agent modeling has gained context awareness application to machine to machine interaction. A well defined methodology, previously applied to human to machine interaction, now can be adopted for smart devices, that behave like humans. Another evidence of the emergence of the Internet of Things technology nowadays comes from the everyday life experience. The Internet of Things is the key for the practical implementation of innovative software systems for the ubiquitous computing. Thanks to all these technologies, Smart devices (like the Nest Thermostat or the Apple Watch) are currently more and more integrated among them and they are becoming invisible servants for final users. As a proof of this new technological era, we can think about how the usage of the Siri tool has become an automated and unconscious mechanism in looking for a telephone number, in reaching a specific destination, or in driving home heating, to understand the potentialities of merging context awareness to the Internet of Things in a convergent and ubiquitous platform. The enormous amount of smart devices, currently deployed in the world, have also to deal with an easy knowledge representation of sensed context, in order to provide new mechanisms to automate daily tasks, understanding the behavior of end-users within the surrounding environment. On the other hand, the rapid growing number of smart devices deployed has a drawback in the future proliferation of high level context models, possibly coupled to lower context levels. What emerges from the current study is the necessity to easy the management of multiple contexts, to be used by upper level applications. The dynamic contextualization solves this kind of issues, distinguishing from the total amount of features, captured from the surrounding environment, and the context model that is closely related to the issue to be solved. Deep profiling on context aware usage enhances the development of context aware services, that can simply use an abstraction layer to properly manage underlying context models. What can be deduced is that the customization of context aware services to the user is a key process to narrow the gap between smart devices and their daily usage. In this dissertation, the definition of high level scenarios have been determined by applying decision trees, for their huge potentialities expressed in dynamic context extraction. Applications of these concepts were used in…

▼ Il presente lavoro è focalizzato sullo sviluppo di nanocompositi multifunzionali innovativi basati sull'uso di una struttura gerarchica. A questo scopo, nanofibre polimeriche sono state prodotte per electrospinning. Questo processo utilizza un' alta tensione (circa il 10-20 kV) per caricare elettricamente una soluzione polimerica per la produzione di fibre ultra-sottili. Due diverse applicazioni sono stati proposte per le membrane termoplastiche ottenute. Nella prima, esse sono state utilizzate per fabbricare laminati compositi tenacizzati e nanorinforzati (utilizzando MWCNT) mediante Resin Transfer Molding (RTM) e altre tecniche di infusione. Mentre nella seconda applicazione, tali membrane sono state modificate con nanoparticelle inorganiche e utilizzate come membrane attive per filtrazione dell'acqua. La necessità di tenacizzare materiali compositi si pone perché essi sono soggetti a delaminazione lungo piani interlaminari. La soluzione proposta a questo problema è stato l'uso di nanofibre che possono essere abbastanza piccole da rinforzare regioni della matrice che si trovano tra strati adiacenti del laminato. A questo scopo sono stati elettrofilati diversi polimeri e sono stati utilizzati come tenacizzanti in laminati compositi. La caratterizzazione di questi laminati, modificati con nanofibre, mostra proprietà termo-meccaniche simili a quelle dei sistemi ottenuti utilizzando la procedura standard. Inoltre, al fine di conferire altre funzionalità quali resistenza al fuoco, lightining-strike, auto-sensing, ecc al composito, sistemi di resine epossidiche con nanocariche sono stati studiati e caratterizzati. Parlando di membrane per la filtrazione dell'acqua, attualmente, membrane polimeriche sono per lo più utilizzate per applicazioni di filtraggio grazie alle loro buone proprietà e bassi costi rispetto alle membrane inorganiche. Di conseguenza, i meccanismi di filtrazione di queste membrane si basano principalmente sugli effetti meccanici come setacciatura, quindi nessuna rimozione chimica delle sostanze tossiche può essere realizzata, questo porta ad effetti di fouling che limitano le prestazioni della membrana. L'idea è stata quella di sviluppare le membrane attive per il filtraggio dell'acqua, caratterizzate da un effetto combinato, setacciatura, proprietà foto-catalitiche e proprietà antibatteriche. A questo scopo, nanofili di ZnO cristallino sono stati cresciuti con un processo chimico da un bagno di deposizione sulle fibre PES ES. Le membrane ibride ottenute mostrano una buona attività fotocatalitica. Inoltre, membrane di PES antibatteriche sono state ottenute da un procedimento one step a partire da una soluzione polimerica con nanoparticelle d'argento precursori. La conversione da precursori argento a nanoparticelle di argento è confermata dalla spettroscopia UV-vis.

▼ The thesis is divided into five chapters: the first four chapters cover the state of the art review on wood plastic composites, lignin and the recycling of bioplastics. The fifth chapter cover the experimental work of the thesis. In chapter fifth the materials and methods used are firstly presented followed by the discussion on the results obtained. The research work performed during the PhD was focused on the development of novel eco-compatible thermoplastic composites. The experimental work was based on the use of two polymer matrices: polypropylene and poly(lactid acid). Polypropilene is not biodegradable but by the addition of a lignin based polymer the carbon biocontent was increased obtaining a formulation readily available and suitable for applications. The results presented on these blends outlined an increased thermal stability and mechanical resistance due to the addition of the lignin based system. This result is promising for the application of this blend in the automotive field. Many automotive parts, such as for example the under hood parts, require improved thermal performances that can be fulfilled by the proposed approach. To overcome the problem of the use of petroleum based plastic the use of PLA was investigated in the research. PLA can be synthetized starting from sugar resulting in a ecofriendly matrix. PLA can be composted so it is a viable option to improve the ecocompability of polymers. However, PLA has an high cost of production which, since now, limited its acceptance in mass production. Therefore, to reduce PLA cost and, at the same time, improve the mechanical and thermal properties the addition of lignin was studied. The results obtained showed that, as for PP, lignin is a potentially good additive. However, the results showed some processing issues due to the thermal stability of PLA which was negatively affected by the reactive moiety of lignin. The results obtained confirmed that combining natural fillers (i.e. lignin) with polymers synthetized by natural sources (i.e. PLA) promising blends can be obtained. However, processing should be optimized to minimize the degradation. To achieve such goal, a feasible process could be to chemical modify the lignin structure or the PLA matrix. Lignin is a multifunctional polymers thus, the approach could be oriented to link moiety which can reduce the interaction with the ester group of PLA. In addition to the improvement of the thermal stability of PLA/Lignin blends future work will be oriented to the use of such blends as matrix for natural fiber composites. This further development will be pursued to obtain sytems suitable for structural applications.

▼ The recently discovered flash sintering technique has shown that the application of a sufficiently large dc electric field (E-field) to a ceramic during sintering can cause sintering at temperatures several hundred degrees below conventional temperatures with sintering rates that allow for sintering in seconds rather than hours. This technique has already been demonstrated in wide range of ceramic materials including ionic conductors, electronic conductors, semi-conductors and insulators. The application of this techniques to a large range of materials and the dramatic lowering of sintering temperatures and times means this technique has the possibility to revolutionize the ceramics field. Because the field of flash sintering is still young, the dominant mechanisms are still yet to be identified. So far, the mechanisms active during flash sintering remain only hypothetical. The key to the mechanism is that it must connect two phenomena controlled by different species: conductivity, which is determined by the fast moving species, and sintering, which is controlled by the slowest moving species. At this point the primary hypothesis is that the high E-fields used cause the nucleation and separation of Frenkel defects allowing for both high sintering rates and high conductivities. This work aims to identify the mechanisms involved in the flash sintering of cubic 8 mol% yttria stabilized zirconia (8YSZ). This materials has been selected because it was one of the first materials show flash sintering properties, and that it has been very well characterized because of its use as a fast oxygen ion conductor. This work began with the construction and initial testing of flash sintering equipment. Mechanistic investigations were performed on fully dense presintered samples of various grain sizes and single crystalline samples subject to the voltages similar to those used during flash sintering at constant temperatures between 600°C and 1000°C. Because flash sintering has a sintering component and electrochemical component, dense samples were used to remove the sintering so observations can be made only on the electrochemical behaviors during these electrical treatments. Additionally, the range of E-fields used for flash sintering of green 8YSZ samples was increased by an order of magnitude from the 150 V/cm to 2250 V/cm. Treatment of fully dense and single crystal samples show that the electrolytic reduction of ZrO2 to ZrO2-δ give I-V relations and power dissipations that are similar to those observed in flash sintering of powder samples. Flash sintering using E-field up to 2250 V/cm reveals several relationships between temperature, E-field, current density and power dissipation and their relation to the onset of sintering and densification. Most importantly the onset of sintering can be determined by the power relationship TOnset = 2440 E-1/5.85, where TOnset is the furnace temperature when flash sintering starts in K and E the applied E-field. Based on these observations, a new mechanism based on electrolytic… Advisors/Committee Members: Sglavo, Vincenzo.

▼ Milling is one of the most important and common processes widely used in manufacturing industry, which is a very competitive environment. For this reason, manufacturing companies are facing many different challenges. The offering of a variety of high quality products, the restriction of production time and costs, the increase of productivity, and the need for flexibility of production are the goals that manufacturers have to consider and achieve in order to succeed in their field. These aspects relate to the process study, optimization and control, and in recent years many attempts to find possible solutions and techniques to manage these steps in a proper way have been done. The first solution that a lot of enterprises were motivated to research and utilize relates to the application of the finite element modeling (FEM) techniques to study manufacturing processes or to highlight behaviour of products, for example of cutting tools, during the design phase. The second technique deals with the manufacturing process control, and is aimed at the increasing of automation level of modern production systems by evolving them towards the paradigm of Intelligent Manufacturing. The present work is focused on the study and evaluation of the effectiveness of both techniques. The first part of the research presented in this thesis is dedicated to the study of the application of Intelligent Manufacturing Systems to milling processes. In particular, in the Chapter 1 it is discussed the improvement of the artificial operator called Evaluation and Perception Controller (EPC) built by the Mechatronics group of the University of Trento within the national project Michelangelo in 2013. In this thesis it is proposed to improve the performance characteristics of the EPC system in terms of the process quality, described by the surface roughness value. In particular, it is proposed to associate the surface roughness term to the scallop height value, and to include a model that describes the mechanism of scallop height formation into the Optimal Control Problem formulation. Chapter 2 of this work is related to the application of FEM techniques to study milling processes. In particular, in this section the influence of CAD cutting tool models (STEP and STL) on 3D FEM AdvantEdge prediction accuracy in terms of the average and maximum cutting forces, and deformed chip thickness and curvature radius values are studied. In addition, this part of the thesis includes also the discussion of the problems related to the application of 2D FEM modeling techniques to study the influence of cutting tools geometries on the feed and tangential cutting forces that act in three-dimensional cutting processes. Chapter 3 of this thesis is dedicated to the development of a model suitable for prediction of cutting forces that act in non-tilted and tilted side down-milling processes performed with end mills. The development of this model has two purposes. First of all, it can be included into the EPC controller, thus extending the field of the possible… Advisors/Committee Members: Bosetti, Paolo.

▼ Thanks to the revisit property of the Earth observation satellites, a huge amount of multitemporal (MT) images are now available in archives. Such kind of images allows us to monitor land surface changes in wide geographical areas according to both long term (e.g., yearly) and short term (e.g., daily) observations. Evolution on the acquisition sensor technology has resulted in the availability of MT and multispectral satellite images with: i) Very High spatial Resolution (VHR) (e.g., Quick-Bird, WorlView-2) and, ii) very high temporal and high spatial resolutions (e.g., Sentinel-2 (S2)). Images acquired by such sensors allow for a detailed geometrical and temporal analysis when compared to medium or high spatial and temporal resolution data. Nevertheless, factors like satel-lite revisit period, the possible competing orders of different users on the satellite pointing (for VHR images only), the limited life of a satellite mission, and weather conditions can lead to: i) lack of enough images acquired by a single sensor to perform MT analysis (VHR case), and ii) lack of regular and continuous Time Series (TS) to perform short term MT analysis (very high temporal and high spatial resolution sensors case) at the level of small objects. Both problems arise from the application requirements on temporal resolution and are being of particular interest in the last years. Two main solutions to the above mentioned problems can be considered: i) use of multisen-sor VHR optical images to replace the missing acquisitions when a single VHR sensor is considered and; ii) development of regression techniques to reconstruct regular and continuous TS from both high temporal and very high temporal resolution sensors. In the literature, most of the MT analysis techniques have been designed to work with: i) VHR images acquired by single sensors, and ii) multispectral images acquired by high spatial resolution sensors, but with low temporal resolution or very high temporal resolution, but with low spatial resolution. Therefore, the effectiveness of ex-isting techniques when applied to the complex MT problems in both VHR multisensor and very high temporal resolution images is reduced. Accordingly, the goal of this thesis is to develop novel tech-niques for the automatic analysis of MT multispectral satellite images such that images acquired by multisensor VHR and very high temporal resolution sensors can be analyzed. The thesis provides four main novel contributions to the state-of-the-art. The first three contribu-tions address the problems arising from the analysis of multisensor VHR multispectral images, whereas the fourth one deals with the problems faced while working with long TS acquired by sen-sors with high spatial and very high temporal resolutions. The first contribution presents an ap-proach for unsupervised CD in multisensor MT VHR images, where the possible sources of noise/changes are studied in detail and a strategy to mitigate them at the levels of pre-processing and feature extraction is presented. In the second… Advisors/Committee Members: Bovolo, Francesca, Bruzzone, Lorenzo.

▼ The usage of PM steels in industry, claims for continuous efforts in research and development. For this purpose, the world biggest part manufacturer, GKN Sinter Metals and the Department of Industrial Engineering of University of Trento started a cooperation to investigate the wear and contact fatigue properties of PM steels. Wear is one of the most important factors that limit the life of engineering components in different ways. In this research two very common phenomena, dry sliding and contact fatigue behavior of PM parts have been investigated. In the first part of the work dry sliding behavior of Fe-Mo-Cu-C and Fe-Mo-Cu-Ni-C steels were investigated. This study was done to investigate the influence of Ni on dry sliding behavior of PM steels. Ni-rich constituent is expected to decrease wear resistance, due to a localized plastic deformation which reduces the load bearing capacity of the surface. Once the effect of the presence of Ni has been assessed, in the second part of the work dry sliding wear resistance of two Ni-alloyed sintered steels, differing for Ni content, was investigated to highlight any effect due to the amount of this alloying element. Based on experimental results, a procedure for the design of dry sliding wear resistant parts was proposed as well. In the second part of the work the contact fatigue behavior of three different steels was investigated. The aim was the proposal of a conservative approach to predict the contact fatigue behavior of different sintered and heat treated steels, based on the nucleation of the fatigue crack. The model is developed by calculating the maximum local stress from the theory of the elastic contact and the matrix yield strength from the microhardness of the steels, under different mean Hertzian pressures. Effect of shot peening on contact fatigue behavior was also investigated. Two different types of shot peening, ceramic or steel+ceramic, were considered. Stress and strength calculations were made based on the local approach on contact fatigue, which was validated in the second part of the work.

▼ A recognized consequence of population aging is a reduced level of mobility, which undermines the life quality of several senior citizens. A promising solution is represented by assisitive robotic walkers, combining the benefits of standard walkers (improved stability and physical support) with sensing and computing ability to guarantee cognitive support. In this context, classical robot control strategies designed for fully autonomous systems (such as fully autonomous vehicles, where the user is excluded from the loop) are clearly not suitable, since the user’s residual abilities must be exploited and practiced. Conversely, to guarantee safety even in the presence of user’s cognitive deficits, the responsibility of controlling the vehicle motion cannot be entirely left to the assisted person. The authority-sharing paradigm, where the control authority, i.e., the capability of controlling the vehicle motion, is shared between the human user and the control system, is a promising solution to this problem. This research develops control strategies for assistive robotic walkers based on authority-sharing: this way, we ensure that the walker provides the user only the help he/she needs for safe navigation. For instance, if the user requires just physical support to reach the restrooms, the robot acts as a standard rollator; however, if the user’s cognitive abilities are limited (e.g., the user does not remember where the restrooms are, or he/she does not recognize obstacles on the path), the robot also drives the user towards the proper corridors, by planning and following a safe path to the restrooms. The authority is allocated on the basis of an error metric, quantifying the distance between the current vehicle heading and the desired movement direction to perform the task. If the user is safely performing the task, he/she is endowed with control authority, so that his/her residual abilities are exploited. Conversely, if the user is not capable of safely solving the task (for instance, he/is going to collide with an obstacle), the robot intervenes by partially or totally taking the control authority to help the user and ensure his/her safety (for instance, avoiding the collision). We provide detailed control design and theoretical and simulative analyses of the proposed strategies. Moreover, extensive experimental validation shows that authority-sharing is a successful approach to guide a senior citizen, providing both comfort and safety. The most promising solutions include the use of haptic systems to suggest the user a proper behavior, and the modification of the perceived physical interaction of the user with the robot to gradually share the control authority using a variable stiffness vehicle handling.

▼ Inertial measurement sensing technology with the capability of capturing disease-relevant data has a great potential for improving the current clinical assessments and enhancing the quality of life in patients with neuro-developmental and neuro-degenerative diseases such as autism spectrum disorders (ASD) and Parkinson's disease (PD). The current clinical assessments can be improved by developing objective tools for the disease diagnosis and continuous monitoring of patients in out of clinical settings. To this end, it is necessary to develop automatic abnormal movement detection methods with the capability of adjusting on new patients' data in real-life settings. However, achieving this goal is challenging mainly because of the inter and intra-subject variability in acquired signals and the lack of labeled data. The research presented in this thesis investigates the application of deep neural networks to address these challenges of abnormal movement detection using inertial measurement unit (IMU) sensors with case studies on stereotypical motor movements in ASD and freezing of gait in PD patients. In this direction, this thesis provides four main contributions: i) A convolutional neural network (CNN) architecture is proposed to learn discriminative features which are sufficiently robust to inter and intra-subject variability. It is further shown how the proposed CNN architecture can be used for parameter transfer learning to enhance the adaptability of the abnormal movement detection system to new data in a longitudinal study. ii) An application of recurrent neural networks and more specifically long short-term memory (LSTM) in combination with CNN is proposed in order to incorporate more the temporal dynamics of IMU signals in the process of feature learning for abnormal movement detection. iii) An ensemble learning approach is proposed to improve the detection accuracy and at the same time to reduce the variance of models. iv) In the normative modeling framework, the problem of abnormal movement detection is redefined in the context of novelty detection and it is shown how a probabilistic denoising autoencoder can be used to learn the distribution of the normal human movements. The resulting deep normative model then is used in a novelty detection setting for unsupervised abnormal movement detection. The experimental results on three benchmark datasets collected from ASD and PD patients illustrate the high potentials of deep learning paradigm to address the crucial challenges toward real-time abnormal movement detection systems using wearable technologies.

▼ It is quite common, in the advances on scientific research, to witness how material properties are exploited toward sensing applications in order to realize novel devices with high performances and tunable characteristics. The synthesis of materials that are not in nature but that are rea-lized in chemical laboratories is often a response to such a requirement. In particular meta materials and, in general, those materials made by the aggregation of several components to result into a multi-phase compound, are often very flexible and can provide very interesting performance in many different application fields. Among these, magnetic materials have gained great relevance thanks to the possibility of controlling many of their features via external magnetic fields but also to the fact that their presence, position or space distribution, is easily detectable by using magnetic sensors. In this Thesis an innovative approach to the development of com-plex devices made by multiple sensing parts together with actuators, and an integrated micro-fluidic system are considered. The basic concept here is the use of new materials, called ferrofluids or magnetic fluids, made by a suspension of magnetic nanoparticles in a carrier fluid; several different devices have been developed and are shown here in order to demonstrate the possibility to use ferrofluids as a core material to realize both the actuating section of a fluidic system and the sensing. The devices realized have been developed as laboratory prototypes and as proofs of concept of the ideas that have been first conceived, and then mathematical and numerical modeled prior to be designed as experimental devices. Due to the intrinsic magnetic nature of the ferrofluids, a briefly introduction on basic concepts about magnetism is discussed in Chapter 1. A classification of materials in nature according to their magnetic behavior is reported, together with some details about the two fundamental source of magnetism: permanent magnets and electromagnets. Finally the main typologies of magnetic sensors commercially available are discussed. In Chapter 2 the magnetic fluids are presented, together with their applications both in the market and in the research world. The main forces acting on a ferrofluid mass are discussed and modeled. In Chapter 3 the attention is focused toward sensors realized during this Ph.D. research activity: a gyroscope, a displace-ment/acceleration sensor, a flow sensor and an inclinometer are dis-cussed, together with their physical model and with the experimental characterization. In Chapter 4 research results on ferrofluids when used in actuators are presented. Plungers, valves and a position control system for ferrofluids drop in water have been developed. Two devices are presented: a pump in which a ferrofluid mass is controlled by an array of electromagnets, and a path tracking system, in which a mass is moved along a pre-defined path by a matrix of electromagnets. The implementation toward integrated device is nowadays of paramount importance…
